رِجَالٌ لَّا تُلْهِيهِمْ تِجَـٰرَةٌ وَلَا بَيْعٌ عَن ذِكْرِ ٱللَّهِ وَإِقَامِ ٱلصَّلَوٰةِ وَإِيتَآءِ ٱلزَّكَوٰةِ ۙ يَخَافُونَ يَوْمًا تَتَقَلَّبُ فِيهِ ٱلْقُلُوبُ وَٱلْأَبْصَـٰرُ Qur’an An-Nur (24:37)Rijalun la tulheehim tijaratun wala bayAAun AAan thikri Allahi waiqami alssalati waeetai alzzakati yakhafoona yawman tataqallabu feehi alquloobu waalabsaru
Lit., "bargaining" or "selling" or "buying and selling" (bay') - a metonym for anything that might bring worldly gain.
For this rendering of the term zakah, see surah {2}, note [34].
See footnote for 7:46.
"Remembrance of Allah" is wider than Prayer: it includes silent contemplation, and active service of Allah and His creatures. The regular Prayers and regular Charity are the social acts performed through the organised community.
Some renderings suggest the effects of terror on the Day of Judgment. But here we are considering the case of the righteous, whose "fear" of Allah is akin to love and reverence and who (as the next verse shows) hope for the best reward from Allah. But the world they will meet will be a wholly changed world.
